Abstract Infrared spectra in the 100–15000 wavenumber region (0.67–100 μm) of some ionic (as LiF) and semiconducting (as Ge, Si, GaAs) powders and crystals are reported. The experiment involves the use of a photoacoustic cell as an accessory to a multiple scan averaging Michelson interferometer. The results show the advantages of studying impurities in powders, and surface properties, particularly since the technique is immune to scattering induced errors.
